Notes:
1.
Permanent device damage may occur if ratings in the “Absolute Maximum Ratings” section are exceeded. This is a stress rating only and functional
operation is not implied for conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum
ratings conditions for extended periods may affect device reliability.
2.
The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.
3.
Thermal performance assumes exposed pad is soldered (or equivalent) to the device’s most negative potential on the PCB.
4.
Due to the limited drive capability, use for input of the same package only.
5.
The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.
6.
VIH (minimum) not lower than 1.2V.
